Non-contact inductive charging mouse pad

The present invention relates to a mouse pad, and more particularly to a non-contact inductive charging mouse pad.

The mouse is a very common and commonly used computer input device that locates the cursor on the current screen and uses the buttons and scroll wheel to manipulate the screen elements at the position where the cursor passes. With the advancement of the times, the mouse has gradually evolved into a wireless input device to improve the convenience of operation and carrying.

Most of the current wireless mouses use batteries as a source of power, but often face the battery is dead or there is no battery to prepare for, so that the wireless mouse can not be activated in time, for the workers who fight every second, or heavy users such as e-sports players, etc. It is impossible to accept that the mouse loses power at an important moment and it takes time to replace the battery.

In order to avoid the above situation, there is a manufacturer to design a mouse pad with a wireless charging module. Referring to Figures 1 and 2, there is a new patent No. M507013 of the Republic of China, which discloses a wireless charging mouse pad body and a mouse combination comprising a mouse 3 and a mouse pad body 1.
